Clean energy leadership


For decades, SMUD has been a leader in clean energy, innovation, technology, renewable energy and customer programs. Today, our 2030 Zero Carbon Plan, adopted in 2021, serves as our official Integrated Resource Plan (IRP). We’ve made significant progress on our 2030 Zero Carbon Plan by committing to more than 1,400 megawatts of new clean energy resources since 2022 and advancing major solar and storage projects that move our region closer to a carbon‑free future.

A lot has changed since we adopted the Zero Carbon Plan more than 5 years ago. Rising resource costs, tariffs, supply chain challenges, loss of renewable tax credits, incentives and millions of dollars in grants are a huge challenge to the affordability of our Zero Carbon Plan. Advances in technology, particularly hydrogen and carbon capture and sequestration, have been much slower than expected. Our natural gas plants are needed to ensure we continue to provide reliable and affordable service to our customers. Our plants are some of the cleanest and most efficient in the state, which means they support regional decarbonization because they produce less emissions than other plants. Despite these headwinds, our progress is significant.

We expect to get 80% of the way to zero carbon in our power supply with all we have planned today and our commitment to decarbonization remains firm. We’re taking a balanced approach to continuous decarbonization that prioritizes affordability, reliability and sustainability. This fall, we’re launching our updated IRP process, a public, data‑driven effort to holistically reassess evolving conditions and refine our long‑term roadmap for reducing carbon emissions to reflect today’s realities. We’ll move forward with a focus on balancing affordability, reliability and sustainability for our customers.

Leading the nation

Our transition to a clean energy future is anchored on our longstanding commitment to provide safe and reliable power with rates among the lowest in California. We believe successful and continuous decarbonization requires balancing environmental goals with affordability, grid reliability and the needs of our growing region. We won’t compromise on this commitment.

As a leader in climate innovation, SMUD’s helping to position the Sacramento Region as a destination choice for forward-thinking, environmentally conscious businesses and a model for others around the nation to follow.

Through implementing our Community Impact Plan, we’re working to ensure our most under-resourced customers are part of this journey and reap the benefits of a clean energy future.

Carbon reduction progress

We’ve made great progress since developing our 2030 Zero Carbon Plan in 2021. We’ve completed several projects in solar, battery storage and geothermal, adding about 590 megawatts of new renewable and storage capacity with 840 megawatts more signed under power purchase agreement to come online between 2026-2030 and thousands more clean energy megawatts under evaluation. That’s a total of about 1,430 megawatts, which is 130% of what we’ve added in the past 2 decades, in about half the time. 

While proven clean technologies such as wind, solar, battery storage, geothermal energy and demand response continue to advance our carbon reduction goals, some emerging technologies have not matured as quickly as anticipated. Technologies such as hydrogen and carbon capture and sequestration continue to hold long-term promise but are not yet developing at the scale, cost or pace originally expected.

As part of our IRP planning process, we're reassessing these assumptions and evaluating the most practical, cost-effective pathways to continue reducing emissions while maintaining affordability and reliability.

Partnerships and grants are also critical as we scale new and emerging technologies, while keeping our rates among the lowest in California. Through a variety of grants, SMUD and our partners have secured critical funding to help deploy advanced smart meter grid technologies and increase the number of EV chargers at multi-family complexes, among other things. However, the funding landscape continues to evolve. In some cases, federal grant opportunities that utilities and communities were counting on have been reduced, delayed or withdrawn, creating additional challenges for deploying emerging technologies and infrastructure.

Why is SMUD focused on reducing carbon emissions?

Carbon emissions contribute to global warming, which leads to extreme weather events, rising sea levels and other environmental challenges that have devastating effects on present-day communities as well as future generations

We live in one of the most polluted cities in the country. A recent report by the American Lung Association gave the Sacramento-Roseville area an F based on days of unhealthy and unsafe levels of air pollution in the ozone layer.

Reducing carbon brings benefits locally and globally. It improves our local air quality, overall health and supports economic development through creating new clean energy job opportunities.

We can’t do this without you

Our customers, community and partners are at the heart of what we do. By reducing carbon emissions, we’re helping create a cleaner and healthier region for all.

We’re all part of the solution. We offer generous rebates and incentives, programs, digital tools, education and many resources for our customers to make smart-energy choices so everyone can take action that helps move us all toward a brighter, cleaner future.

What is our 2030 Zero Carbon Plan

Our 2030 Zero Carbon Plan, adopted in 2021, serves as our official Integrated Resource Plan (IRP). This fall, we’re launching our updated IRP process, a public, data‑driven effort to holistically reassess changing market conditions, technology advancements, customer needs and policy developments. The outcome will help guide our ongoing commitment to continuous decarbonization while ensuring we maintain a balanced approach that prioritizes affordability, reliability and sustainability.

Natural gas generation repurposing

Today, our five natural gas plants provide low-cost, reliable, around-the-clock power that supports regional grid stability, particularly during periods of peak demand and extreme weather. SMUD's natural gas fleet is among the cleanest and most efficient in the nation, and these facilities continue to play an important role in maintaining reliability and support regional decarbonization as more renewable energy resources are added to the grid.

While still needed for reliability, reducing greenhouse gas emissions from our power plants can help us continuously decarbonize. That’s why in 2025, we completed our Cosumnes Power Plant turndown project, a significant project that supports operational flexibility and delivers up to a 27% greenhouse gas reduction (~100,000 metric tons) along with ~$10 million in annual fuel savings.

Proven clean technology

We'll expand the use of our existing carbon-free energy technologies like wind, solar, hydro, biomass, geothermal energy, battery storage and demand response. Since 2021, we’ve committed to over 1,400 megawatts of new carbon-free renewable energy to our power supply. On the customer side, we offer extensive programs and services to support a clean energy transition.

 ""

New technology and business models

We regularly explore new and emerging technologies - like power-to-gas technology, hydrogen and methane, long-duration batteries and carbon sequestration - that are either currently unknown or are not ready for large scale adoption due to price, reliability or other factors. This work will help us identify potential partnerships and business models like virtual power plants and launch pilot projects and programs to test and prove new and emerging technologies and develop paths for prioritizing technology adoption and scaling. 
 ""

Financial impacts and options

Our road map will identify cost ranges and rate impacts associated with expanding our existing proven clean technologies and for researching and piloting new technologies and business models. We’re focused on making sure achieving a zero-carbon future is possible at a reasonable cost that minimizes rate increases for our customers, limiting rate impacts to the annual rate of inflation. We’ll do that by identifying savings and pursuing partnerships and grants that support this work.
